Abstract
- Aluminum is a widely distributed element and plays an indispensable role in our lives, but excessive intake of Al3+ can cause potential harm to human health. Highly selective methods for the rapid detection of Al3+ are urgently needed. Here, a novel "turn on" fluorescent probe L based on Schiff-base of 2-hydroxy-1-naphthaldehyde and 8-aminoquinoline was obtained in an excellent yield. Probe L presents significant properties such as rapid response, good stability, wide pH range, simple synthetic operation, and provides an efficient strategy for the highly selective detection of Al3+ in an aqueous solution of DMSO/H2O (7:3, v:v). According to Job's curve and fluorescence titration, probe L with Al3+ forms a 2:1 ratio of complex, and the lowest limit of detection is 3.23 × 10−8 mol/L. The possible combination mode for probe L with Al3+ was proposed by comparison with the changes of 1H NMR and FTIR spectra of L and its complex. In addition, the potent applicants for probe L were also investigated, and indicated that it could conveniently be made into a series of sensor strips and applied to rapidly detect trace Al3+ in traditional Chinese medicine.
